BUTTON-FEEDING MECHANISM FOR BUTTON-SETTTNG MACHINES.

Specification of Letters Patent.

Application filed August 5, 1915. Serial No. 43,851.

T 0 all whom it may concern Be it known that I, FREDERICK E. STAN- nor, a citizen of the United States, residing at ater-bury, in the county of New Haven and State of Connecticut, have invented a certain new and useful Improvement in Button-Feeding Mechanism for Button-Setting Machines, of which the following is a full, clear, and exact description.

This invention relates to'the type of button-setting machine illustrated in the case of Stanley and Leggett, filed May 10, 1915, Serial No. 27 ,Oii, and has special reference to the button-turning feature by which-the buttons as they come one by one from the'hopper or turret through the raceway or chute in an edgewise position, are given a quarter turn so'as to present them horizontally to the means by which they are placed in operative relation to the tack or other fastening for attachment to a garment or other article.

The invention consists of means by which the slotted cylindrical piece of the button turner is given its turning movement to turn a button from its edgewise position into the horizontal position required in order to be properly delivered to the mechanism to receive the tack or rivet by which it is subsequently set, said means comprising a crank arm or disk applied to the button turner and connected with a vibrating lever, as I will proceed now to explain and finally claim.

In the accompanying drawings illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1 is a side elevation of sufficient of a'button setting machine of the type referred to, to illustrate the application of the present invention. Fig. 2 is a top plan view of all that portion of the machine shown in. Fig. 1 above the tack manipulating portion. Fig. 3 is a front elevation of the main features of the invention detached. Fig. 4: is a perspective view of the cylindrical piece of the button turner and ejector detached.

1 is the head of the machine, on which is mounted the main shaft 2, and the other parts of the machine, including the button turret (not shown) from which the button chute 3 extends, and the tack or rivet turret from which a chute 4: extends to the tack or rivet delivery, positioning, and setting means, all of which may be substantially as in the case referred to.

at the delivery end of the button chute is an auxiliary chute 5, at the bottom of which is a housing 6 in 'whichis arranged the cylindrical piece 7 of the button turner, said piece having the transverse diametrical slot 8 at one end adapted to be turned up vertically to'receive a button edgewise from the button chute after it has been allowed to escape therefrom by means of the cutoff or escapement 9 and also to turn the thus received button a quarter turn so as to present it horizontally and in position to be transferred to the button holder, as in the case referred to, to be thence presented to the means for applying the rivet or tack to it in order to fasten the button to the goods, or to set it. The cylindrical piece 7 has applied to its end opposite its slotted end a crank disk or crank arm 10 provided with a wrist pin 11 which is engaged by link12 pivoted to a lever 13 which in turn is pivoted at 1.4: to the head. This lever 13 is provided at its opposite end with a cam-roller15 which is acted upon by a cam 16 on the main shaft 2 and reacted upon by a spring 17, or other suitable means, so that as said lever 13 is rammed. a y. a, rare.

button in the necessary horizontal position which it must be given in order to cooperate with the tack or rivet applying means for setting purposes. Thus a very simple, direct and positive acting button turner is provided.

The cylindrical piece of the button turner is provided with a longitudinally reciprocating ejector rod 18 having the head 19 of suitable form, which is located in the slot 8, and this rod is provided with a grooved collar 20 at its opposite end which is engaged by a tracker 21 swiveled on the end of a vibrating lever 22 which is pivoted at 23 on a bracket 2 1 fast to the head, said lever having a cam-roller 25 at one end engaged by a cam 26 on the shaft 2 and having its other end engaged by a spring 27, the cam and spring serving to vibrate said lever and thereby reciprocate the ejector. The ejecting motion of the ejector serves to move the button from the button turner after the turner has been rotated to the button holder whence it is delivered to the tack applying mechanism.

The cut-ofl' 9 is reciprocated horizontally by any suitable means, such for example as the bell crank lever 28 actuated in any suitable way, as by a cam slide 29 having a camroller 30 cooperating with a cam 31 on the main shaft 2, this cam slide having its return movement imparted by any suitable means, such as the spring 32. The lever 13 may have its upward movement arrested or.

adjusted by means of a set screw 33.

Variations in the construction and arrangement of parts may be made within the spirit and scope of the invention as herein claimed.

What I claim is 1. In a button setting machine, a button chute down which the buttons travel edgewise, an auxiliary chute at the delivery end ofthe button chute and terminating in a housing, a cut-off or escapement for controlling the delivery of the buttons one by one to the auxiliary chute from the button chute, and a button turner for receiving the thus delivered buttons and turning them from the edgewise to a horizontalposition and comprising a transversely slotted cylindrical piece arranged in the path of descent of the 1 button, a crank mechanism fixed on said cylindrical piece, and means to turn said crank mechanism. V

2. In a button setting machine, a button Copies 01' this patent may be obtained for chute down which the buttons travel edgewise, an auxiliary chute at the delivery end of the button chute and terminating in a housing, a cut-off .or escapement for control ling the delivery of the buttons one by one to the auxiliary chute from the button chute, and a button .turner for receiving the thus delivered buttons and turningthem from the edgewise to a; horizontal positionand comprising a transversely slotted cylindrical piece mounted in said housing and capable of turning therein axially, a crank arm on said cylindrical piece, a vibrating lever and a link connecting the crank arm and vibrating lever.

' 3.. In a button. setting machine, a chute by which the buttons are delivered edgewise, an auxiliary chute arranged at the delivery end of said chute and having a housing at its bottom, areciprocating cut-oil or escapement to control the delivery of the buttons one by one to the auxiliary chute from the button chute, a button turner arranged in said housing and having a transversely slotted end to receive the button edgewise from the button chute, and means to rotate said turner to change the position of the button from edgewise to flatwise, comprising'an eccentrically arranged Wrist pin on said turner, avibrating lever, and a link coni nectingthe wrist pin and lever.

In testimony whereof I have hereunto set my hand this 29th day of July, A. D. 1915.
